This achievement is not exactly easy. You have to score a hit on an opponent at least once with each kick you can do. There are a total of 8 kicks. Once for each direction on the d-pad or stick.
just think of the d-pad as a compass and the following will help you. all attacks are assumed you are facing your opponent from the left. If you flip over your opponent and are now on the other side, obviously you would need to reverse the directions to do the right kick.
north - jump kick
north east - flying high kick
east- side kick
south east - Low kick
south - foot sweep
south west - lying on back high kick.
west - High kick
north west - looks like a jumping hook kick.
best to try this on the first character that you fight called buchu
wait for him to fly over to you and as he lands, you should be able to get a jump kick in. Then if you are lucky, you can follow up with a flying high kick. Now just start going around the d-pad as you get your hits. So you would do a side kick, then a low kick, then a foot sweep. The last 2 you would need are high kick and flying hook kick. If you do it right, you can land combinations of like 4 moves. Dont expect to get this on the first try. Just remember any of the kicks like jump kick, flying high kick and flying hook kick are not as easy to land as the others.
